Chrome tanning is a method used to preserve animal hides and turn them into leather. This process involves soaking the hides in a solution containing chromium salts, which helps to stabilize the collagen fibers in the skin. As a result, the leather becomes more durable, flexible, and resistant to water and heat. The chrome tanning process is faster than traditional methods, taking only a few days to complete. It is widely used in the leather industry due to its efficiency and the high-quality leather it produces. However, concerns about the environmental impact of chromium have led to increased scrutiny and the development of safer alternatives.
